Etymology: Eptatretus: hepta (Gr.), seven; tretos (Gr.), perforated (i.e., with holes), referring to seven gill apertures on what would later be described as Homea banksii (=E. cirrhatus) [range within genus is 6-14 pairs of gill apertures] (See ETYFish); burgeri: In honor of German physicist and biologist Heinrich Bürger (ca. 1804-1858), who collected type (See ETYFish).
Eponymy: Dr Heinrich Bürger (1804/06*-1858) was a German physicist and biologist employed by the Dutch government. [...] (Ref. 128868), visit book page.

Short description Claves de identificación | Morfología | Morfometría
Six pairs of gill pouches and gill apertures in a rarely variable linear arrangement. Branchial slime pores, 4-6. The last left gill aperture (GA) is closely adjacent to but separate from the pharyngocutaneous duct (PCD). Eyes spots are prominent (Ref. 31545). White mid-dorsal line prominent; fused cusps 3/2, total cusps 40-42; total slime pores 81-92 (Ref. 51420).
Found in the sublittoral zone (Ref. 11230). Usually buries itself in bottom mud (Ref. 26686). Migrates into deeper water to spawn (Ref. 51361, 51374). This is the only member of the family having a seasonal reproductive cycle (Ref. 51361). Food fish in Japan. Hide is processed into leather and exported worldwide, usually as 'eel' leather.
Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Copulatory organ absent. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Ref. 51361 ). However, there was a presumption of 0.1% or even less that this species manifests functional hermaphroditism (Ref. 51416).
This is the only member of the family having a seasonal reproductive cycle (Ref. 51361).

Estimates based on models
Preferred temperature (Ref. 123201): 11.1 - 23.4, mean 18.8 °C (based on 182 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00204 (0.00094 - 0.00444), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278): 4.5 ±0.80 se; based on food items.
Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
